Hi Hoai Anh,
I've asked a telecommunication engineer, and he said me that MSC support load balancing.
Thanks for your answer.

I'm not quite sure what do you mean with MSC.
Anyway, I assume your environment is like
[PSTN (Public Switched Telephone Network)]<------------------>[DTM
Switch]<-----------SS7 (PRI line)---------------->[Asterisk
Box]<----------------VoIP (SIP/IAX etc...)---------> IP net
If you mean MSC Mobile Switching Center it could look like
[GSM Network]<------------------------->[MSC]<----------------- SS7
-------------------->[Asterisk
Box]<---------------------VoIP---------------------->IP net
Normally, the DTM Switch or MSC should be configurable for
load-balancing and failover.
Point code is for SS7 networking like IP address for IP networking.
